After I have set up all the media folders the server has spent some time indexing and then it crashed. After that every attempt to restart it leads to an immediate crash. The following section of the crash log may contain a clue to the developers:

when you enable logging - it should state in the log file which file it scans when it crashes.You the could verify that it is that exact file by copying this file into a single folder and only sharing that folder. If the server crashes again - this is the file that is problematic.
